Relative Stability from the Nyquist Plot: Relative Stability from the Nyquist Plot - The considerations discussed above provide information about the absolute stability of the system, i.e., whether the system…
Nyquist Criterion: Nyquist Criterion - This stability criterion enables one to establish the stability of a system using a graphical procedure in the frequency domain. Here also there is no…
Routh Hurwitz Criterion: The Routh Hurwitz Criterion states that the system is stable if the Routh table has no negative elements in the first column. The roots of the characteristic…
Polar Plot for Frequency Response: One of them is the Polar Plot for Frequency Response representation. The transfer function in the frequency domain is obtained by substituting jω for s…
Transient Response of Closed Loop Drive System: The Transient Response of Closed Loop Drive System is of fundamental importance and must be investigated in detail. The time response of a…
Closed Loop Control of DC Motor: Closed Loop Control of DC Motor - The dynamic behaviour of a system is described by a set of differential equaÂtions. On many occasions…
Block Diagram of Electric Drive System: It is normal practice in control engineering to represent a control system by means of a Block Diagram of Electric Drive System, with a…
Introduction Control Techniques in Electric Drives: An electric drive is a well established industrial drive as it has several adÂvantages and special features. Its Control Techniques consists in starting, speed…
